I solved the issue by deleting the Xcode 1000 version directory for both ArKit Face and ArKit Plug in from my Library directory in Unity

• the dir is place here
  /Users/anyata/AndroidStudioProjects/flutter-unity-arkit-demo/unity/ARDemoApp/Library/PackageCache/com.unity.xr.arkit-face-tracking@3.0.0-preview.3/Runtime

you could do the same for the ArKit PlugIn make sure to delete the unused version of XCode for me it was Xcode version 10 since i use version 11. After deleting the dir Unity didn't confused anymore and succeed the build

Hope i save someone else to bug in these issue
